An empirical comparison of natural-father and stepfather family systems.

This study examined the family system differences between 40 volunteer natural-father and stepfather families. Family triads consisting of the husband, the wife, and a child whose age ranged from 12 to 15 years were studied. Four instruments were used: (a) the Family Concept Q-Sort; (b) a Semantic Differential; (c) a demographic questionnaire; and (d) an interaction-reaction questionnaire. Analyses of variance on the data obtained from the Q-sorts and the Semantic Differentials indicated that stepfather family systems are different from natural-father family systems along several salient dimensions including psychological adjustment, satisfaction with family, reciprocal understanding, and perceived goodness and potency. It was concluded that the differences between the family systems in terms of their interpersonal relations and perceptions affect the entire stepparent family system and its ability to function adequately.     

An empirical comparison of rhythm in language and music

Musicologists and linguists have often suggested that the prosody of a culture's spoken language can influence the structure of its instrumental music. However, empirical data supporting this idea have been lacking. This has been partly due to the difficulty of developing and applying comparable quantitative measures to melody and rhythm in speech and music. This study uses a recently-developed measure for the study of speech rhythm to compare rhythmic patterns in English and French language and classical music. We find that English and French musical themes are significantly different in this measure of rhythm, which also differentiates the rhythm of spoken English and French. Thus, there is an empirical basis for the claim that spoken prosody leaves an imprint on the music of a culture.     

An empirical comparison of methods of communality estimation

This paper shows the formulation of nine methods of estimating the unknown communalities. Each of these methods has been used on experimental data and the results tabulated for comparison. The results show that the most accurate approximations are obtained from the Centroid No. 1 and theGraphical methods.The author wishes to express his appreciation to Professor L. L. Thurstone for his advice and for providing the facilities of the Psychometric Laboratory for this investigation.     

An empirical comparison of restricted and general latent distance analysis

Latent distance analysis provides a probability model for the non-perfect Guttman scale; the restricted latent distance structure is simpler to compute than the general structure. Since no sampling theory for latent structure analysis is available, the advantages of the general structure cannot be expressed formally. The two structures are compared in terms of their fit to fifteen sets of empirical data. The computation schemes used are summarized.     

An empirical comparison between some models for multidimensional scaling

Abstract.— The results of three methods for multidimensional scaling—Torgerson's metric analysis, a non-metric method (TORSCA), and a method dealing with individual differences in multidimensional scaling (INDSCAL)—were compared in experiments on rhythm experience and on perception of sound quality. The INDSCAL analysis seemed to be the most adequate method for treating the data in these experiments.     

An empirical comparison of 5 standard procedures for one-dimensional scaling

Scales on the badness of 10 offenses/crimes are derived by using the five most common scaling methods: averaging of the badness-ratings of the stimuli on an 11-point scale; mean ranks of complete rankings of the 10 stimuli; Thurstone scales for complete forced-choice and constant-sum pair comparisons, resp.; and ratio scales derived from pairwise ratio judgments for all pairs. From older investigations, a logarithmic correspondence of ratio scales and Thurstone or average ratings, resp., can be predicted. The data corroborate this prediction. They show furthermore that the ratio scale has an exceedingly close, logarithmic relation to each of the other four scales. We therefore conclude that, once a universe has been shown to be scalable, a scale can be constructed very economicaly by simply averaging ratings.     

Stimulus-driven attentional capture: An empirical comparison of display-size and distance methods

Four experiments examined attentional capture by colour as assessed by two different investigative methods. Subjects performed a visual search task for a vertical-target line embedded among tilted-distractor lines, presented inside 4, 8, or 12 coloured discs. Interestingly, when the colour singleton was task irrelevant, and data were analysed by means of the display-size method combined with the zero-slope criterion, no evidence for attentional capture by colour was found. However, when data were analysed by means of the distance method, which consists of monitoring the spatial relationship between the target and the singleton, results showed that the target was found faster and/or more accurately when it was inside the singleton than when it was in a nonsingleton location. This provided evidence for a stimulus-driven attentional capture. In addition, the application of signal detection methodology showed that attentional capture, as revealed by the distance method, resulted from a perceptual modulation at the singleton location, rather than from a criterion shift. We conclude that, at least with the kind of stimuli used here, the display-size method combined with the zero-slope criterion is less than ideal for investigating how static discontinuities can affect the automatic deployment of visual attention.     

The structure of emotion: An empirical comparison of six models

There are a number of conflicting approaches to the problem of the relationship between different emotions. One category of models focuses on the valence of emotional experience and typically reports evidence for dimensional approaches to emotion. A second category of models argues for the possibility of discrete basic emotions, but typically focuses on evidence from emotion systems other than conscious experience. In the present study, a list of emotion terms was drawn up that were derived conceptually from a set of basic emotions. A group of participants filled out a questionnaire that asked how much in general they experienced each of the emotions. A structural equation modelling approach was then used with the resultant dataset, an approach that permitted the comparison of six different models that ranged from the positive-negative affect models to models of discrete basic emotions. The analyses gave support for a set of five basic emotions but only when these were allowed to correlate with each other. Implications for theories of emotion are considered.     

An empirical comparison of several interval estimation procedures for coefficient alpha

Following a general introduction to Tukey's Jackknife technique and the construction of approximate confidence intervals, ten variants of the procedure are defined for giving interval estimates for coefficient alpha. A data base of known population characteristics was generated and used to compare the robustness of the ten Jackknife alternatives with Feldt's well-known sampling theory based upon the assumptions of normality. The empirical results indicate that out of the ten variants, defined by five transformations and two methods of data subdivision, only two are justifiable competitors to Feldt's approach.     

Predicting group-level outcome variables: An empirical comparison of analysis strategies

This study provides a review of two methods for analyzing multilevel data with group-level outcome variables and compares them in a simulation study. The analytical methods included an unadjusted ordinary least squares (OLS) analysis of group means and a two-step adjustment of the group means suggested by Croon and van Veldhoven (2007). The Type I error control, power, bias, standard errors, and RMSE in parameter estimates were compared across design conditions that included manipulations of number of predictor variables, level of correlation between predictors, level of intraclass correlation, predictor reliability, effect size, and sample size. The results suggested that an OLS analysis of the group means, with White’s heteroscedasticity adjustment, provided more power for tests of group-level predictors, but less power for tests of individual-level predictors. Furthermore, this simple analysis avoided the extreme bias in parameter estimates and inadmissible solutions that were encountered with other strategies. These results were interpreted in terms of recommended analytical methods for applied researchers.     

The production and verification tasks in mental addition: An empirical comparison

We respond to A. Baroody's comment (1984, Developmental Review, 4, 148–156) with an empirical comparison of the production and verification tasks. With the exception of performance at the first grade level, the two tasks yield essentially identical conclusions. The results of an adjunct task, in which the rate of mental counting was assessed, suggest that children as young as second grade are relying on memory retrieval to a significant degree. In contrast to Baroody's speculation, there appear to be no widespread difficulties associated with results from the verification task. Furthermore, the task permits a more analytic examination of performance and underlying mental process than is afforded by the production task. We conclude by reiterating the empirical support for a model of fact retrieval, and suggesting that accessibility of the arithmetic facts is the basic factor which underlies both fact retrieval and procedural knowledge performance.     

Overt integrity tests versus personality-based measures of delinquency: An empirical comparison

This study examined the ability of both an overt integrity test and a personality-based measure of delinquency to predict on-the-job theft and counterproductivity. A heterogeneous sample of 105 employees anonymously completed both tests and a criterion checklist that included a 9-item theft subscale and a 12-item counterproductivity subscale. Results indicated that the overt integrity test was a superior predictor of both on-the-job theft and drug abuse compared to the personality-based measure. The overt integrity test was also a slightly better predictor of general counterproductivity. These findings and their implications are discussed.     

Assessment of creativity with the ACL: An empirical comparison of four scales

Several scales have been developed from the Adjective Check List to assess creativity, with almost no comparative data to evaluate them. In this study, two samples, one of research scientists and one of advanced architecture students, were assessed using the A CL scored for the Domino, Gough, Schaefer, and Yarnell scales of creativity. The results indicated a fair amount of equivalence among the four scales, with a tendency for the Domino and the Gough scales to have better convergent and discriminant validity.     

An empirical comparison of three variants of the AHP and two variants of conjoint analysis

This paper provides an empirical comparison of two methods of attribute valuation: the analytic hierarchy process (AHP) and conjoint analysis. Variants within each approach are also examined. The results of two empirical studies indicate that the methods differ in their predictive and convergent validity. Within the AHP methods no significant difference in predictive validity was found. Within the conjoint methods, the ranking method significantly outperformed the rating method. The difference in predictive validity between the AHP and conjoint methods was significant in the second study but not in the first study, suggesting superior performance of the AHP over conjoint analysis in complex problems.

Evidence for bivariate systems: An empirical test of appetition and aversion across domains

Research in diverse domains of psychology has independently identified two behavioral systems, one concerned with obtaining positive outcomes, the other concerned with avoiding negative outcomes. This basic distinction, described in different domains of inquiry with varying terminology, may be integrated within a single appetitive–aversive systems model. The present research was designed to examine the viability of the appetitive–aversive distinction as an organizational construct underlying various particular measures and concepts. In four studies, individual difference measures from different domains were examined with exploratory (Study 1) and confirmatory (Studies 2–4) factor analyses. We expected and found that measures tapping sensitivity to rewards or positive outcomes would load on a common appetitive latent factor, whereas, measures tapping individual differences in sensitivity to punishment or negative outcomes would load a common aversive latent factor. Results strongly supported the hypothesized two-factor structure over alternative models and indicated that the latent appetitive and aversive variables accounted for about half the variance in the observed variables.

Selection of variables in exploratory factor analysis: An empirical comparison of a stepwise and traditional approach

The purpose of this study was to investigate and compare the performance of a stepwise variable selection algorithm to traditional exploratory factor analysis. The Monte Carlo study included six factors in the design; the number of common factors; the number of variables explained by the common factors; the magnitude of factor loadings; the number of variables not explained by the common factors; the type of anomaly evidenced by the poorly explained variables; and sample size. The performance of the methods was evaluated in terms of selection and pattern accuracy, and bias and root mean squared error of the structure coefficients. Results indicate that the stepwise algorithm was generally ineffective at excluding anomalous variables from the factor model. The poor selection accuracy of the stepwise approach suggests that it should be avoided.

An empirical examination of the mechanisms mediating between high-performance work systems and the performance of Japanese organizations

The resource-based view of the firm and social exchange perspectives are invoked to hypothesize linkages among high-performance work systems, collective human capital, the degree of social exchange in an establishment, and establishment performance. The authors argue that high-performance work systems generate a high level of collective human capital and encourage a high degree of social exchange within an organization, and that these are positively related to the organization's overall performance. On the basis of a sample of Japanese establishments, the results provide support for the existence of these mediating mechanisms through which high-performance work systems affect overall establishment performance.
